First Jose Canseco Athletics Jersey , we had viruses, then Trojans, then rootkits. AdWare made its presence felt. Now, with the advent of Cloud Computing and businesses increasingly relying on the Internet as a business tool, we have ransomware. The coming Internet of Things makes for a very scary future of cyberattacks and cybersecurity battling it out for supremacy.
First Joe Morgan Athletics Jersey , a definition of ransomware: Simply put, ransomware is a type of malware that blocks user access to their data. Simple attacks are can be reversed by a specialist. More advanced malware encrypts user data, followed by a ransom demand requesting payment before is it decrypted. It is usually categorised as a denial-of-access attack.
By denying users access to data, businesses can be shut-down until the malware is removed and the data recovered. One study found that an attack usually resulted in at least two days of downtime. For small businesses, the downtime could cost an average of just over $8 Jed Lowrie Athletics Jersey ,500 per hour.
Ransomware attacks are usually delivered via a Trojan embedded in a legitimate file. Infected email attachments (Microsoft office files are a favourite, followed by scanned image files) are often the favoured delivery medium.
A final kick-in-the-teeth is that ransomware usually has a time limit within which the ransom needs to be paid. If not paid in this time window, the user data becomes unrecoverable.
If we take 2016 as a baseline, the statistics are bad enough already. The FBI reckon that over $209Million was paid to ransomware criminals in Q1 2016 alone, expecting it to become a billion dollar business by the end of the year:
The number of infections increased to over 56 Glenn Hubbard Athletics Jersey ,000 in March 2016 with the advent of the Locky Trojan; Infected emails increased by 6000% over 2015 40% of all spam email was infected with ransomware. IBM also found that 70% of victims paid the ransom. While the average payment was around $1,000, 50% paid more than $10,000 and 20% more than $40,000.
Most businesses Dennis Eckersley Athletics Jersey , around 70%, when faced with a ransom demand paid up. They considered it easier and more cost effective to pay up than face the downtime and uncertainties of trying to fix it themselves. That obviously does not include those businesses that did not report an attack. And like other forms of ransom, there is no guarantee that you will get your data back and the likelihood of your being targeted again just increased.
